Through Soviet Union and Mikhail Gorbachev

The agency was a military service governed by army laws and regulations, in the same fashion as the Soviet Army or the MVD Internal Troops. While most of the KGB archives remain classified, two online documentary sources are available. Its main functions were foreign intelligence, counter-intelligence, operative-investigative activities, guarding the state border of the USSR, guarding the Soviet leadership, preserving the security of government communications as well as combating dissent and separatism within Soviet society.

On 3 December 1991, the KGB was officially dissolved. It was succeeded in Russia by the Foreign Intelligence Service (SVR) and what would later become the Federal Security Service (FSB). Following the 1991–1992 South Ossetia War, the self-proclaimed Republic of South Ossetia established its own KGB, keeping the unreformed name. In addition, Belarus established its successor to the KGB of the Byelorussian SSR in 1991, the Belarusian KGB, also keeping the unreformed name.

History

Restructuring in the MVD following the fall of Lavrentiy Beria in June 1953 resulted in the formation of the KGB under Ivan Serov in March 1954.

Secretary Leonid Brezhnev overthrew Premier Nikita Khrushchev in 1964. Brezhnev (in power: 1964–1982) was concerned about ambitious spy-chiefs – the communist party had managed Serov's successor, the ambitious KGB Chairman, Aleksandr Shelepin (in office: 1958–1961), but Shelepin carried out Brezhnev's palace coup d'état against Khrushchev in 1964 (despite Shelepin not then being in the KGB). Brezhnev sacked Shelepin's successor and protégé, Vladimir Semichastny (in office: 1961–1967) as KGB Chairman and reassigned him to a sinecure in the Ukrainian Soviet Socialist Republic. Shelepin found himself demoted from the chairman of the Committee of Party and State Control in 1965 to Trade Union Council chairman (in office 1967–1975).

In the 1980s, the Soviet Union glasnost provoked KGB Chairman Vladimir Kryuchkov (in office: 1988–1991) to lead the August 1991 Soviet coup d'état in an attempt to depose President Mikhail Gorbachev. The failed coup d'état and the collapse of the USSR heralded the end of the KGB on 3 December 1991. The KGB's modern-day successors are the FSB (Federal Security Service of the Russian Federation) and the SVR (Foreign Intelligence Service).
